Technical Field

The present invention relates generally to fasteners for securing bundled elongate articles, such as wires, cables, hoses, pipes, optical fibers, conduits, climbing plants, harness-like straps, and the like, to a support structure. More particularly, the present invention relates to a strap retainer device for securing an elongated article extending from and through a fastener along a support structure or mounting surface.

Background

Flexible cable ties are widely used to secure elongate items such as wires, cables, hoses and pipes in a compact, secure bundle. Typically, such cable ties include a head portion and a flexible strap that terminates in a tail portion. In use, the tail of the heel strap is looped around the elongate article and the tail is inserted through an optional slotted opening in the mounting socket and then through an aperture in the head of the cable tie. Next, the tail is pulled to cinch the strap around the article, thereby securing the article into a compact, ordered bundle. A jaw mechanism in the head aperture secures the strap against pull-out.

In many applications, it is sufficient to hold the elongated items in a bundle. Such applications may include, for example, stationary electronic devices that remain in one place and experience little or no motion or vibration during use. Also in the long distance traversal of bundles such as wires, cables, hoses, tubes, etc. on stationary or mobile equipment, it is required to compress the bundles to a small diameter by applying cable ties at repeated distances (e.g., every 12 inches). In other applications, it is not only required or desirable to secure the items in a bundle, but also to secure the resulting bundle to a supporting chassis or frame. For example, in cars, trucks, airplanes, boats, and other vehicles where the bale may be subjected to severe shock and vibration, such applications are also common. In other applications (e.g., in buildings) where vibration may not be a significant consideration, it is still desirable to secure cables, hoses, pipes, etc. to a fixed support structure.

Generally, the strap and mount will be manufactured as separate items; however, because the strap and mount are used together, it is advantageous to position the articles close together before they are used to bundle an article or articles. In some forms, such as that described in U.S. patent No. 8,028,962, the items may be loosely connected together, or the cable tie may be integrally formed with the mounting block as in the present invention.

Likewise, many known mounts do not provide a high proportion of mechanical advantage and high holding strength when the mount is mounted into a threaded bore in a mounting surface. Furthermore, known christmas tree or fir tree mounts, such as those disclosed in U.S. patent No. 5,921,510 to Benoit et al and U.S. patent No. 4,396,329 to Wollar, do not contemplate the use of threaded holes, and thus leave room for improvement. Furthermore, known tie down fixtures may not provide sufficient holding force and tightness to the support surface for adequately supporting the tied items, or provide holding force within threaded through holes or threaded blind holes. Known fir tree mounts typically engage the bottom edge of the through-hole (see, e.g., fig. 5A) and are sized to be compatible with commonly sized drill holes, such as 1/4 ", 5/16", 3/8 ", 6mm, 7mm, 8mm, 9mm, for example. However, the internal diameter of the drilled and tapped threaded hole does not necessarily correspond to the dimensions described above; thus, the fir tree branches of the known device may be larger or smaller than the diameter of the threaded holes. This disadvantage causes problems with insertion force and fixation strength, as the branches are crushed or otherwise deformed, thereby reducing the fixation strength (see, e.g., fig. 4A). Further, known fir tree mounts do not provide a fit and engagement that matches the root diameter of the helical thread pattern.

Furthermore, known mounting devices including integrally formed cable ties do not account for self-centering of the bundle and mounting holes. In bundle installation, self-centering with the mounting holes is useful for bundle installations requiring uniform alignment of the bundles along the centerline. The present device provides self-centering whereby designers of automobiles and other equipment use CAD software to use the positioning of the mounting holes to route the saddle from the centerline of the mounting hole to the centerline of the mounting hole. In contrast, when the conventional prior art uses a self-attaching fir tree with integral cable ties, misalignment between the bundle and the mounting hole is encountered. This deviation can occur when the saddle passes on both sides of the mounting hole. This establishes an uncertainty about the required overall length of the saddle when the engineer designing the saddle path does not know on which side of the mounting hole the deviation will occur. Furthermore, the bundle diameter of most saddles varies depending on how many wires and what wire diameter is to be fixed. The variable bundle diameter together with the offset creates another degree of uncertainty about the required overall length of the saddle for lifting. These factors create uncertainty in the user when calculating the required saddle length for use in automotive or equipment applications.

The self-centering feature of the present device allows a user (such as a designer of automobiles and other equipment) to align the centerline of the saddle with the centerline of the mounting hole, thus reducing the above-mentioned uncertainty and making further comparisons among the differences shown in fig. 5, 5A and 5B. The self-centering feature further allows automotive and equipment engineers to determine a more precise length of the desired saddle by using CAD software to arrange the routing channels. The present invention provides an improved mounting assembly to address the above-mentioned problems, to provide improved mounting attachment strength and improved saddle access.

Disclosure of Invention

The present invention provides an improved bale securing and mounting device for securely securing and supporting a baled item on a support surface. The device provides a mounting base with an aperture that interacts with a flexible strap having serrations for binding elongated items. The tether may be integrally formed with the device. The aperture contains wedge-shaped jaws that provide a serrated ratcheting action when the strap tail behind the strap is inserted into the aperture during the binding process. Reversing the direction of the strap engages the teeth of the pawl to wedge against the teeth of the strap, thereby preventing withdrawal of the strap.

The invention may also include a diaphragm spring and a bifurcated mounting stud or post extending downwardly from the mounting block in opposite directions of the cable tie. The diaphragm spring provides tension and stability to the support surface when the branched mounting stud is inserted into a hole in the support surface. In addition, the branches extend radially and in a spiral pattern from the central portion of the stud. The branches are arranged in a branching array with the branching array positioned about the screw axis approximately every 90 degrees. The distal ends of the legs are preferably sized to match and engage the root diameter of the cutting thread profile in the hole to be engaged. Each successive branch end is located at a predetermined height corresponding to and following the pitch pattern of the particular helical thread of the thread profile to be engaged. The height of corresponding branches in adjacent rows of branches follows a helical pitch pattern so that the branches mate and engage the roots of the threads when inserted into a bearing surface having threaded holes.

The invention may also include a self-centering feature to position and secure the bundle in alignment with the mounting hole. A particular self-centering feature includes a tie head having an integrally formed article support surface, such as a saddle structure, opposite the mounting stud. The strap extending from the head of the lace may include a flexible hinge member. The hinge member is adapted to move and flex so that the strap conforms to the diameter of the bundle to be secured. Tensioning the strap around the bundle creates a circumferential force against the bundle to self-center the bundle on the article support surface, which in turn is centered on the mounting stud. The mounting studs are aligned with the mounting holes.

This unique structural arrangement thereby secures the bound item such that the longitudinal axis of the bundle is perpendicular to the axis of the mounting stud. In applications where space, weight and cost are paramount, it is advantageous to self-center the mounting holes with the co-linear bundles. Further, in harness fixation applications, self-centering allows the bundle to be aligned on the harness centerline rather than being offset or adjusted to one side or the other of the mounting hole, as is typical in conventional integrally formed cable tie mount mounting arrangements. Self-centering provides consistency in coaxial mounting orientation that allows for simple CAD modeling of the harness with predictable harness lengths, overall shortest harness lengths, less space required, and lower cost. The present invention self-centers bundles of any bundle diameter that can be secured by means of a cable tie aligned with the mounting hole.

The mounting assembly according to the present invention may include any combination of the above features. Further, the mounting and self-centering threading features may be provided in connection with a unitary product or as separate components. Further, the mounting seat may be provided in conjunction with alternative fastening means, such as clips, clamps, mounting saddles, or other compatible fasteners.

Detailed Description

While the invention has been disclosed as being exhaustive and precise to enable those skilled in the art to practice the invention, the embodiments of the entity disclosed herein are merely exemplary of the invention, which may be embodied in other specific forms. Although preferred embodiments have been described, the specific details may be varied without departing from the invention as defined by the claims.

Fig. 1-5B illustrate a prior art mounting device 200 that either includes an integrally formed cable tie 12 or is shown in combination with a cable tie 12. As shown particularly in fig. 5, 5A and 5B, known devices 200 are not typically arranged to self-center the longitudinal axis L of the bundle 80 and the vertical axis M of the mounting stud in the mounting hole. As shown, particularly in fig. 5A and 5B, as the bundle diameter changes, the Offset Distance (OD) also changes. Further, the prior art mount 200 with offset placement and branch mounting portions may not provide adequate attachment in both threaded and non-threaded holes. For example, fig. 4A shows a typical prior art mounting device 200 having a branch mounting portion. As shown, the individual branches 260 deform in the bore and improperly engage the threads 104. The present invention overcomes these deficiencies, which are discussed below.

Attention is now directed to fig. 6, where it can be seen that a mounting device 10 according to the present invention can secure an elongated article or bundle 80 to a support surface 100 (see dashed lines). An elongated strap 12 having a strap 16 and a strap head 18 may be integrally formed with the mounting device 10 for wrapping and securing around the bundle 80, thereby securing the bundle 80 to the mounting device 10, which in turn secures the mounting device 10 to the support surface 100. Lace portion 12 is also seen to include a hinge member 70 located adjacent head portion 18. The bundle 80 may be comprised of a single item or several items, such as wires, cables, hoses, pipes, wire harnesses, or other elongated items. It will be appreciated that the bundle 80 may comprise a bundle of individual wires or cables, rigid or flexible conduits, hot or cold fluid transport tubes or hoses. The bundle 80 may also be received within the bore of a conventional tubular conduit. Likewise, the bundle 80 may be of various sizes and also be accommodated by the device 10. As also shown in fig. 6A, the device 10 further centers the bundle 80 on the device 10, with the axis L of the bundle 80 perpendicular to the axis M of the device 10, as will be discussed below.

Fig. 7 is a partial perspective view of the mounting device 10 shown in fig. 6A-6C, but showing the hinge member 70 in a rest position. As shown, the mounting device 10 may include an integrally formed strap portion 12, the strap portion 12 having a relatively flat object support surface 20 (such as the illustrated saddle structure 22), an elastic portion 40 located below the support surface 20 on the head 18, a hinge member 70, and a mounting portion 50 extending downwardly from the support surface 20 and the elastic portion 40. The support surface 20 may be integrally formed with the lace head 18, with the support surface 20 providing support for the bundle 80. The tie head 18 includes an aperture 28, the aperture 28 having a pawl 30 or other means for providing a ratcheting attachment to the strap 16. Extending from head 18 are a resilient portion 40 and a mounting portion 50. It should be understood that support surface 20 and lace head 18 are not limited to any particular orientation. Each of these sections will be described in detail with reference to the following drawings.

As seen in fig. 6-8A, the mounting device 10 may be provided with a hinge member 70. As shown, hinge member 70 is preferably integrally formed with lace portion 12 and adjacent head portion 18. Focusing particularly on fig. 7, it can be seen that hinge member 70 includes a region 72 of reduced thickness to allow for dexterous movement of hinge member 70. The hinge member 70 is adapted to flex about the reduced thickness region 72 and allow the strap 12 to wrap around and conform to the bundle 80, thereby securing the bundle 80 without applying uneven forces to the bundle 80. The hinge member 70 allows the strap 12 to apply a uniform circumferential force to the bundle 80, thereby centering the bundle 80 against the flat support surface 20. The bearing surface 20 is in turn centered on the mounting stud 50. This unique structural arrangement allows the bundle 80 to be secured and self-centered such that the longitudinal axis (L) of the bundle 80 is perpendicular to the axis (M) of the mounting portion 50 (see fig. 6 and 6A). The features of the hinge member 70 in combination with the support surface 20 enable the device 10 to align the bundle 80 with a centerline of the mounting hole 102 that is coextensive with the axis (M) of the mounting portion 50. This is in contrast to known devices 200 in which the bundle 80 is off axis (M) or is to be corrected, as shown in fig. 1-5A. In addition, the hinge member 70 allows the lace 16 to move and flex to conform the strap 16 to the diameter of the bundle 80 to be secured. The tensioned strap 16 exerts a circumferential force on the bundle 80 causing the bundle 80 to self-center on the item support surface 20, which in turn centers the item support surface 20 on the mounting stud 50. A uniform circumferential force on the bundle 80 can center the bundle 80 on the bearing surface 20, the axis (M) of the mounting stud 50, and the hole 102. It should be understood that although the drawings show the device 10 mounted with the mounting portion 50 extending downwardly, the device 10 may be mounted in other orientations, for example, extending from the underside of the support surface 100.

With further attention to fig. 7, it can be seen that the mounting device 10 can interact with an integral elongated strap 16 (as shown in fig. 6) prior to securing the strap 16 about the bundled bundle 80. The strap 16 is inserted through the aperture 28 and the pawl 30 provides a ratcheting engagement of the teeth 14 of the strap 16 against the forces encountered when moving or grasping the mounting device 10. The jaws 30 also secure the strap 16 in the ready position so that the strap 16 is in the proper orientation to allow the bundle to be immediately tied or wrapped. The jaws 30 are also visible in the cross-sectional views of fig. 6C and 10. Because the present design contemplates a molding process to form the mounting device 10, the jaws 30 may also be molded such that when the strap 16 is inserted into the aperture 28, the jaws 30 are strong enough to resist movement of the strap 16, while, at the same time, the jaws 30 are flexible enough to flex when the strap 12 secures the bundle 80.

Referring to fig. 7-10, the resilient means 40 is generally comprised of a flexible disk or diaphragm spring 42. As shown, diaphragm spring 42 preferably extends downwardly from lace head 18. The diaphragm spring 42 tapers downwardly and outwardly from a first end 44 at the tie head 18 to a second end 46. 7-10 show the diaphragm spring 42 in a relaxed position; however, when the mounting studs 52 are moved into the holes 102, as seen in fig. 15A-17, the diaphragm spring 42 flexes against the support surface 100 and provides a tight fit with the support surface 100. The diaphragm spring 42 provides a pre-loaded spring tension and further secures the device 10 against the support surface 100. The device 10 is retained within the bore 102 by the force of the branches 60 and the helical arrangement of the branch rows 62a, 62b, 62c, 62 d. The diaphragm spring 42 provides tension and stability to the support surface 100. The view of fig. 11 shows a bottom view of the diaphragm spring 42. As shown, the diameter of the diaphragm spring 42 is preferably greater than the diameter of the mounting stud 52 so that when the mounting device 10 is inserted into the aperture 102 of the support surface 100, the diaphragm spring 42 will flex against the support surface 100 to provide a tight fit. The diaphragm spring 42 shown in the drawings is generally circular and conical; however, the shape and configuration of the diaphragm spring may be any flexible geometric design or arrangement that provides the desired resistance to the resilient portion 40. For example, the diaphragm spring 42 may be comprised of a pyramid shape having any number of sides, each of which may or may not be connected to an adjacent side.

Referring particularly to fig. 7-14, it can be seen that mounting portion 50 includes a mounting stud 52, mounting stud 52 having a proximal end 52a located adjacent lace head 18 and a distal end 52b located opposite proximal end 52 a. Mounting studs 52 extend downwardly from the lace head 18. It is also contemplated that the mounting studs 52 extend downwardly from the resilient portion 40; however, the resilient portion 40 may be arranged to surround the proximal end 52a of the mounting stud 52 without the mounting stud 52 actually being suspended from the resilient portion 40 or the diaphragm spring 42. The above-described arrangements either fall within the scope of the present invention or should not be considered as limiting the invention. As shown, the mounting stud 52 includes a central portion 54 that is substantially coextensive with the lengthwise dimension of the mounting stud 52.

Fig. 8-14 are views particularly illustrating the central portion 54 of the mounting stud 52. As shown, the central portion 54 includes a plurality of radially extending extensions or branches 60. Such an arrangement is commonly referred to as a fir tree mounting stud or a christmas tree mounting stud. As shown, the branches 60 extend radially in a helical thread pattern and extend outwardly from the central portion 54. The legs 60 are longitudinally spaced from one another and taper upwardly toward the lace head 18. The branches 60 are further arranged in branch rows 62a, 62b, 62c, 62d that are spaced about 90 degrees apart about the central portion axis (L). The individual branches 60 in each branch row 62a, 62b, 62c, 62d are uniformly spaced from one another; however, as shown, each of the rows of branches 62a, 62b, 62c, 62d is arranged such that the branches 60 in the respective row of branches 62a, 62b, 62c, 62d lie in parallel planes that extend approximately halfway between the parallel planes formed by two adjacent rows of branches 62a, 62b, 62c, 62d, as will be discussed below.

As can be seen particularly in fig. 12-15, the rows of branches 62a, 62b, 62c, 62d are preferably arranged in a staggered pattern relative to one another about the central portion 54. As shown in fig. 15, each branch 60 includes a distal end 64 sized to mate with and engage the root diameter of the profile of a cutting thread 104 of a threaded bore 102. The distal end 64 of each branch 60 in the branch rows 62a, 62b, 62c, 62d is spaced a predetermined distance, or pitch, from the adjacent branch 60 and its distal end 64 (see FIG. 12). As further seen, the distal ends 64 of the branches 60 adjacent the rows 62a, 62b, 62c, 62d of branches are preferably arranged such that: the virtual spiral path HP may be traced from the first distal end 64 to the corresponding distal end 64 of the adjacent branch row 62a, 62b, 62c, 62 d. The virtual helical path HP is defined by its pitch and helix angle, and is preferably associated with the threads 104 of the threaded bore 102 in which the device 10 may be installed. The views of fig. 15 and 16 particularly show the engagement of distal end 64 with threads 104.

As shown in fig. 12-16, this arrangement of the distal end 64 in the virtual helical path HP allows for a stronger and easier to insert mounting device 10 than previous designs having a symmetrical design. As seen particularly in fig. 15 and 15A, the stud 52 is inserted into the support surface 100 and rotated in the direction of arrow a. The distal end 64 of each branch 60 makes continuous contact with the bearing surface 100, thereby facilitating insertion of the stud 52 as it moves in the direction of arrow B. Further, the helical arrangement of the branches 60 allows for mating and engagement of the branches 60 with the threads 104. Moreover, the staggered spiral pattern of branched rows 62a, 62b, 62c, 62d provides a more secure hold for the device 10 than is possible with typical studs, increasing the force required to remove the stud 52 from the support surface 100 by the many contacted branched distal ends 64. The device 10 can be removed from the hole 102 by rotating the device in the direction of the dashed arrow C. When rotated in the direction of arrow C, the distal ends 64 of the branches 60 ride in the opposite direction across the threads 104 as the device 10 moves in the direction of dashed arrow D.

As can be seen in particular in fig. 16, each successive distal end 64 engages a thread 104 along a virtual helical path HP. Because each branch end 64 engages the threads 104, the device 10 resists extraction from the bore 102 with increased holding strength. In addition, the branches 60 are thin to provide flexibility. Moreover, the branches 60 emanate from the stud 52 at a smaller acute angle relative to the stud 52 (see FIGS. 12 and 14), providing improved holding strength as compared to known symmetrical designs. The above-described reduction in the thickness of the branches 60 strategically allows for positioning and matching the branches 60 to the pitch of the helical thread pattern, as seen in fig. 6C, 15 and 15A, thereby providing more distal end 64 contact points along the threads 104. This arrangement provides a combined, simultaneous engagement effect of all the branches 60 working together, thereby increasing the holding strength of the device 10 more than the known device 200. As shown in these figures, the device 10 provides more distal 64 contact points than conventional symmetrical designs; however, more or fewer contact points at distal end 64 may be provided, and the number of branch rows 62a, 62b, 62c, 62d may vary and still fall within the scope of the present invention. The helical path HP of the present mounting stud 10 provides enhanced engagement of the device 10 by using the contact point of the distal end 64 to improve retention strength within the threaded bore 102.

Another advantage provided by the helical path HP of the structural arrangement of the leg rows 62a, 62b, 62c, 62d is that it allows the legs 60 to be spaced apart for optimal distal end 64 contact with the threaded bore 102. The legs 60 used in the present invention are preferably thin, flexible legs 60 molded at an acute angle relative to the stud 52 and configured to provide a low insertion force, but to transfer a high extraction force to the stud 52. It should be understood that the branches 60 used in the device 10 of the present invention may be of a different shape and design than those shown herein, while still falling within the scope of the present invention. For example, the branches 60 may be of a warped shape, a corrugated design, or other desired shape. Likewise, the stud 52 may be oval or other shape as may be desired for a particular application.

Referring to fig. 9 and 10, the tie head 18 further includes an aperture 28, the aperture 28 having a pawl 30 extending into the aperture 28. When the strap 16 is inserted into the aperture 28, the pawl 30 engages the elongated strap 16 and preferably contacts a plurality of teeth 14 (see fig. 6 and 7) located on the strap 16. The jaws 30 engage the serrations 14 on the strap 16 to hold the strap 16 from being pulled out when secured around the bundle 80. Fig. 9 shows a side view of the mounting device 10, rotated 90 degrees from the view shown in fig. 8. As shown, the width of the central portion 54 is preferably uniform. The uniform diameter of the central portion 54 makes the legs 60 more flexible than previous designs, thereby providing a more secure mounting device 10.

Fig. 9 and 10 also show a pair of shoulders 33 extending upwardly and into the apertures 28. The shoulders 33 are preferably located on each side of the jaws 30. When the bundle 80 is secured (see fig. 6 and 7), the strap 16 will be pulled to flex the pawl 30 and the lace 12 can be tightened around the bundle 80. The shoulder 33 provides substantial resistance against which the strap 16 will abut, thereby securely holding the bundle 80. The pawl 30 is arranged to flex but not interfere with the strap 16 abutting the shoulder 33. In addition, the shoulder 33 forms a recessed channel for the jaws 30 so that the jaws 30 can flex during insertion of the strap 16 while maintaining rigidity to secure the strap 16 in place. The arrangement and number of shoulders 33 and jaws 30 may differ from that shown in the figures.

Fig. 15A-16 show cross-sectional views of the mounting stud 52, which are similar to the view of fig. 10, but showing the device 10 in use and inserted into a support surface 100 having a threaded bore 102. As shown, the branch 60 engages the threads 104 in the bore 102 to prevent its pull-out. FIG. 16 particularly illustrates the manner of engagement of the rows 62a, 62b, 62c, 62d, wherein the offset rows 62a, 62b, 62c, 62d allow the staggered individual branches 60 to more securely engage the threads 104.

Fig. 17 shows the device 10 in use and in combination with a support surface 100 having a reduced thickness and a non-threaded bore 202. When used in this environment, the central portion 54 extends beyond the aperture 202 such that the branches 60 engage the bottom side 204 of the aperture 202. Fig. 17 is a diagram illustrating another example of an environment in which the device 10 may be employed. As shown, the present invention improves upon previous designs and is suitable for use with variable bearing surfaces 100, including threaded or unthreaded bore surfaces, and is also suitable for use in bearing surfaces 100 of varying thickness.

In use, the mounting stud 52 may be driven into the bore 102, 202 by hand using a tapping tool (i.e., a mallet) or by twisting as shown in FIG. 15. When mounting stud 52 enters bore 102, branch 60 engages the sides of bores 102, 202. When the bore 202 is provided with threads 104, as shown and as discussed with reference to FIGS. 15-16, the arrangement of the staggered spiral pattern of rows of branches 62a, 62b, 62c, 62d allows the threads 104 to engage the distal end 64, unlike previous designs. The staggered spiral pattern arrangement of the rows of branches 62a, 62b, 62c, 62d also provides for more secure engagement and retention of the device 10 to the support surface 100 when the device 10 is to be used in a relatively smooth hole 202, as shown in FIG. 17. When the installation device 10 is pulled, the branches 60 prevent such movement, particularly in the longer holes 102, 202 shown, which have been dug or otherwise located in the masonry surface.

The features discussed in this disclosure may be present in a single mounting device 10, or the mounting device 10 may contain one or a combination of the features described and still fall within the scope of the present disclosure. For example, fig. 18 and 19 illustrate the self-centering feature of the article support 20 and the hinge member 70, with the article support 20 being considered as a saddle-shaped structure 22, and the hinge member 70 being combined with alternative mounting portions 50A, 50B. Preferably, the components of the mounting device 10 are injection molded from a strong, durable plastic such as Nylon 6/6.

Fig. 20-24 are perspective views of alternative embodiments utilizing the mounting portion 50 shown in fig. 6-17 and illustrate various article support members. For example, as shown in FIG. 20, the mounting device 110 is shown employing a diaphragm spring 42 and a mounting portion 50 with staggered, helically arranged rows of branches 62a, 62b, 62c, 62 d. A thrust pad 120 is provided which positions the clip 112 or saddle structure a distance offset from the mounting hole (not shown in this view). In contradistinction to the lace 12 used in the previous embodiment, the mounting device 110 of this view includes a wire or cable clamp 112 located on the mounting device 110. Similarly, fig. 21 shows a mounting device 210, which mounting device 210 is designed with a diaphragm spring 42, a mounting portion 50 with spirally arranged rows of branches 62a, 62b, 62c, 62d and also a clip 212 instead of a lace 12. The mounting arrangement 310 shown in fig. 22 comprises a diaphragm spring 42, a mounting portion 50 with spirally arranged rows of branches 62a, 62b, 62c, 62d and an alternative saddle structure 320. Another embodiment includes the use of a friction plate 330. The friction plate 330 provides a resistive force similar to the dog 30 previously described. Fig. 23 shows a mounting device 410 having an alternative structural arrangement of an integral tie strap 12. The mounting device 410 utilizes the diaphragm spring 42 and the mounting portion 50 with the spirally arranged offset rows 62a, 62b, 62c, 62 d. Fig. 24 shows another mounting arrangement 510 utilizing a mounting portion 50 with spirally arranged offset rows 62a, 62b, 62c, 62d, wherein a toothed clip 512 is used to secure the bundle 80 (not shown in this view). As these examples demonstrate, the present invention can be used in many varied structural arrangements.

The foregoing description is considered as illustrative only of the principles of the invention. For example, the strap 12 should be broadly considered to include structure for securing an item to a mounting device, such as the clips 112 and 212 shown in fig. 20 and 21. Likewise, the design of the clips 112 and 212 or other similar concepts should be understood to be incorporated under the apertures previously discussed to interact with the lace 12. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While preferred embodiments have been described, the details may be changed without departing from the scope of the invention, which is defined by the claims.
